污水处理对黑水/灰水中溶解性有机物紫外光谱及荧光光谱特性的影响
Effect of wastewater treatment on ultraviolet and fluorescence spectra of dissolved organic matter in black water/gray water
摘要
Abstract
In order to investigate the variation of the spectral characteristics of dissolved organic matter (DOM) in black and gray water during wastewater treatment and the differences of DOM characteristics in black and gray water between pre- and post-biological treatment, the ultraviolet and fluorescence spectra of DOM in black and gray water were measured and analyzed along the wastewater treatment process. The results showed that the DOM concentration in raw black water was much higher than that in gray water, and the former contained more non-biodegradable organic matters. Biological treatment can effectively remove easy degradable DOM in black and gray water. The membrane separation process in membrane bioreactor system (MBR) can also intercept DOM in black and gray water. Compared with the effluent of black water, DOM concentration in the effluent of gray water was lower, and its main component was saturated organic matter. The polymerization degree of benzene ring carbon skeleton was higher, and the THMs formation activity was lower. The biological treatment process can effectively remove protein and biodegradable humic substances from black and gray water. After biological treatment, the protein peaks of black and gray water disappeared, and the fluorescence intensity of humic acid-like substances in the effluent of black water was higher than that in gray water. In comparison with black water effluent, the effluent of gray water is more suitable for recycling.关键词
